Adjustable-depth crankbait fishing lure

An adjustable-depth fishing lure, of the type used with a fishing line, for use in catching fish at user-selected water depths, comprising in combination:

• b) a buoyant substantially rigid body comprising a first side, a second side, and an internal cavity;
• c) a diving means, located adjacent said first side and said second side of said body, for assisting in forcing said body under the water's surface;
• d) an adjustable-depth means, coupled to said diving means, for adjustably setting the traveling depth of the fishing lure, wherein said adjustable-depth means comprises:
• i) a rotatable shaft extending through a transverse first opening in said body, said shaft being attached to said diving means,
• ii) a first arm, attached to and extending substantially perpendicularly from said shaft, said first arm being structured and arranged for pivoting rotationally within said cavity, and
• iii) (iii) a blocker means, attached to said body, for selectively limiting rotation of said first arm;
• e) a hooking means for hooking the fish;
• f) an attachment means for attaching the fishing lure to the fishing line;
• and
• g) a guard means for preventing accidental changing of said adjustable-depth means.

An adjustable-depth fishing lure, for use in catching fish, of the type used with a fishing line, comprising, in combination:

• b) a buoyant substantially wood body comprising a substantially closed internal cavity and comprising a first opening extending substantially transversely through said body, said body comprising a first side and a second side;
• c) a rotatable shaft extending through said first opening;
• d) a first lateral fin attached to said shaft adjacent said first side of said body;
• e) a second lateral fin attached to said shaft adjacent said second side of said body;
• f) a first arm, attached to and extending substantially perpendicularly from said shaft, said first arm being structured and arranged for pivoting rotationally within said cavity;
• g) a blocker, mounted in said body, wherein said blocker is structured and arranged to selectively limit movement of said first arm;
• h) a hook structured and arranged to hook the fish;
• and
• i) an attachment feature, structured and arranged to assist in attaching the fishing lure to the fishing line.

An adjustable-depth fishing lure, of the type used with a fishing line, for use in catching fish at user-selected water depths, comprising, in combination:

• b) a body comprising an exterior, an internal cavity, a first opening, and a second opening, wherein said body is structured and arranged to attach to a hook and to a fishing line;
• c) at least one fin attached to a first rotatable member wherein said fin is located adjacent said exterior of said body, and said first rotatable member is inside said first opening in said body;
• and
• d) a fin pitch control mechanism comprising a second rotatable member located in said second opening of said body, wherein said pitch control mechanism is structured and arranged so that a selected amount of rotation of said second rotatable member selects the water depth.

An adjustable-depth fishing lure, of the type used with a fishing line, for use in catching fish at user-selected water depths, comprising in combination:

• b) a buoyant substantially rigid body comprising a first side, a second side, and two artificial eyes;
• c) a diving means, located adjacent said first side and said second side of said body, for assisting in forcing said body under the water's surface;
• d) an adjustable-depth means, coupled to said diving means, for adjustably setting the traveling depth of the fishing lure;
• e) a hooking means for hooking the fish;
• f) an attachment means for attaching the fishing lure to the fishing line;
• g) a guard means for preventing accidental changing of said adjustable-depth means;
• h) wherein said diving means comprises a first lateral fin and a second lateral fin;
• i) wherein said first lateral fin and said second lateral fin each comprises an elongated member comprising a top surface and a convex leading edge;
• and
• j) wherein each said top surface adjacent said leading edge comprises a substantially-circular indentation comprising an apex extending for a distance of about ⅛ inch from a plane of said top surface.

An adjustable-depth fishing lure, of the type used with a fishing line, for use in catching fish at user-selected water depths, comprising, in combination:

• b) a body comprising an exterior, an internal cavity, a first opening, and a second opening, wherein said body is structured and arranged to attach to a hook and to a fishing line;
• c) at least one fin attached to a first rotatable member wherein said fin is located adjacent said exterior of said body, and said first rotatable member is inside said first opening in said body;
• d) a fin pitch control mechanism comprising a second rotatable member located in said second opening of said body, wherein said pitch control mechanism is structured and arranged so that rotation of said second rotatable member effects a rotation of said first rotatable member;
• e) wherein said pitch control mechanism further comprises a first arm attached to, and substantially perpendicular to, said first rotatable member wherein said first arm is located within said internal cavity of said body,
• f) wherein said second rotatable member is structured and arranged to be manually rotated with a screwdriver;
• g) a friction fit between said second rotatable member and said body;
• h) depth-selection markers affixed to the exterior of said body;
• i) wherein:
• i) said second opening is substantially parallel to said first opening;
• ii) said pitch control mechanism further comprises a second arm attached to, and perpendicular to, said second rotatable member;
• and
• iii) said second arm contacts, and influences the location of, said first arm.
